C. It consists of sedimentary rock.
Fossils are most commonly preserved in sedimentary rocks because organisms are buried by sediments (mud, sand) in environments like lakes, rivers, and oceans and then lithified. Igneous rocks form from melted rock at high temperatures that destroy organic remains, and a layer formed "a few years ago" would be too recent to contain an ancient fossil.
